Free Bet Blackjack is a blackjack variant in which the casino places an extra bet for the player on a double or split, and dealer 22 pushes the player's remaining hands. Our calculation values a free double on hard 11 against six at 30% of the bet more than a regular double.
What Free Bet Blackjack is
Free Bet Blackjack combines casino-funded additional bets with a trade-off: dealer 22 produces a push instead of the usual dealer-bust win. Your original cash bet remains at risk, so “free” describes the extra bet, not the entire hand.
In regular blackjack, you normally put up more money to double down or split. Here, qualifying hands receive a free bet token instead. The token helps determine your winnings but is not cash you can collect simply because it is on the table.
Wizard of Odds puts the house edge at 1.04% under its rules, detailed below.
Why the free double and free split matter
The free double and free split let you play qualifying hands without funding the additional stake yourself. That reduces your cash exposure compared with making the same additional bet with your own money.
The benefit is conditional. Compare the same double with identical outcome probabilities, and the free double improves the result because a loss costs less. But the full game also includes hands that do not qualify, along with the dealer 22 push that offsets these attractive betting rules.
The house edge calculator can turn the cited 1.04% into an expected loss per bet. That is a long-run average, not a forecast for your next session. For a comparison with another variant that also pushes on dealer 22, see Blackjack Switch rules. Do not carry its rules over to Free Bet Blackjack.
How the free double works
A free double adds a casino-funded stake equal to your original bet, while leaving only your original cash at risk. In the Wizard and New Jersey versions, it applies to hard 9–11 on the first two cards. New Jersey also allows a version with a free double on any number of cards if the casino gives notice (2.10(f)). A hard hand has no ace counted as 11.
Here is the process for a $40 bet:
- You have hard 11 against a dealer six.
- You take the free double: your cash stake stays at $40, and the casino adds an equal free bet token.
- You receive one more card and stand.
- The dealer completes the hand, and the bets are settled.
Educational diagram: outcomes of a free double and a regular double on hard 11 against a dealer six, $40 betEducational example: $40 bet, dealer shows 6. Probabilities from our calculation with an infinite deck and H17.
Distinguish the money returned from your net profit:
| Outcome | Free double | Regular double |
|---|---|---|
| Win | Your original cash stake returns; net profit equals twice the original stake | Both cash stakes return; net profit equals twice the original stake |
| Loss | You lose one original stake | You lose two original stakes |
| Push | Your original cash stake returns; the token is not paid as cash | Both cash stakes return |
The free bet token is part of the hand’s settlement, not an extra cash balance. The probability assumptions and arithmetic for this example appear in the calculation section below.
How the free split works
A free split separates an eligible pair into two hands: your cash bet stays on the first hand, and a casino-funded free bet sits on the second. Each hand is settled separately.
On the cash-funded hand, a win returns your stake plus winnings, a loss takes the stake, and a push returns it. On the token-funded hand, a win pays winnings, but the token itself does not become your cash. A loss or push on that hand produces no cash payment from the token.
You must combine both hands’ results to find the round’s net result, including any additional cash bets. Winning one split hand does not automatically mean the round was profitable.
Eligible pairs depend on the version. Tens are excluded in all three versions below; Nevada also excludes fours. For the separate question of splitting tens, see splitting tens in blackjack. Do not assume that a pair eligible for an ordinary cash-funded split also qualifies for a free split.
What dealer 22 means
The dealer 22 push returns the cash stake without profit on a hand still in play. Exactly 22 is treated differently from a normal dealer bust; it does not rescue a player hand that has already busted.
Player blackjack needs separate attention. Nevada’s rules explicitly preserve its winning payout against dealer 22. That exception concerns an initial two-card blackjack, not every hand totaling 21.
A dealer-22 side bet is a separate wager, not another name for the main-hand push. It is excluded from the calculation here.
Three rule versions: Wizard, New Jersey and Nevada
These are three different versions, not interchangeable parts of one universal rule set. Read each source column as a separate description.
| Rule | Wizard of Odds | New Jersey casino rules | Nevada Rules of Play |
|---|---|---|---|
| Decks | Six | Not stated in the NJ rules | Six or eight |
| Double down | Two cards only; allowed after a split | Free double on the first two cards with hard 9–11 | Any number of cards, including after a split |
| Free double | Hard 9–11 | Hard 9–11 | Hard 9–11 with any number of cards |
| Free split | All pairs except tens | Any pair except tens | Pairs except fours and tens |
| Re-splitting | Up to four hands, including aces | Limit set by the casino (2.11(g)) | Up to four hands |
| Soft 17 | Dealer hits: H17 | Dealer hits: H17 | Dealer hits: H17 |
| Dealer 22 | Push | Push | Remaining hands push except player blackjack |
| Player blackjack | Pays 3 to 2 | Pays 3 to 2 (2.7(d)) | Pays 3 to 2 and still wins against dealer 22 |
| Surrender | Not allowed | First two cards, after the dealer checks for blackjack, at the casino’s option | The source does not state it |
| House edge | 1.04% under these rules | Not stated in the NJ rules | The source does not state it |
The New Jersey provisions are sections 13:69F-2.7, 2.8, 2.10, 2.11 and 2.12 of the state rules, including the any-number-of-cards free double variant (2.10). A table entry saying that a detail is not stated marks a limit of the information available; it does not mean the casino has no rule for it.
What our calculation shows
For the same outcome probabilities, the free double improves expected value over a regular double by the probability of losing, expressed as a share of the original stake. Winning net profit is unchanged, while each loss costs one fewer cash stake.
The calculation uses hard 11, one additional card, then standing. It assumes an infinite deck, dealer hits soft 17 (H17), and dealer 22 pushes; it excludes hands with a dealer natural blackjack or changing finite-deck composition.
| Dealer upcard | P(loss) | Difference from a regular double |
|---|---|---|
| 2 | 34.4% | 34.4% of the original bet |
| 6 | 30.0% | 30.0% of the original bet |
| 10 | 42.1% | 42.1% of the original bet |
| Ace | 43.2% | 43.2% of the original bet |
| Average over dealer upcards | 37.1% | 37.1% of the original bet |
Against six, our calculated probabilities are 54.1% win, 30.0% loss and 15.9% push. Expected value is measured relative to the original bet:
- Regular double: 2 * P(win) − 2 * P(loss), giving 48.3%.
- Free double: 2 * P(win) − P(loss), giving 78.3%.
- Difference: 78.3% − 48.3% = 30.0% of the bet.
The displayed probabilities are rounded to one decimal place; results use the underlying unrounded probabilities. Substituting the displayed values may therefore differ in the final decimal place.
The most influential assumption is the 22 rule: treating dealer 22 as a player win instead of a push raises average free-double expected value from 58.9% to 74.3%. By comparison, having the dealer stand on soft 17 (S17) instead of hitting changes it from 58.9% to 59.1%.
A Monte Carlo check of 2,000,000 hands returned 58.9%, compared with the analytic result of 58.9%. Among deals without a dealer natural, as in the table above, the probability of dealer 22 is about 7.72%. Across all deals, including dealer blackjack, it is about 7.36%; Wizard of Odds gives 0.073536 for six decks with H17. This is a useful cross-check, not proof that infinite- and finite-deck calculations are identical.
Limits and mistakes to avoid
The central mistake is treating a positive expected value for one selected hand as a player advantage across the whole game. This calculation compares two ways to fund a particular double; it is not a complete playing strategy.
The regular basic-strategy chart does not account for free bets. Its decisions cannot automatically be transferred to Free Bet Blackjack, and the probability table above is not a replacement for version-specific basic strategy. The practical rule from Wizard of Odds for its rule set: if you remember one thing, accept every free double and free split opportunity. On a free-bet hand a push is as bad as a loss, which makes that strategy more aggressive than the regular one. Check other versions separately.
Surrender also requires care; see when to surrender in blackjack. New Jersey allows the casino to offer surrender on the first two cards; that does not establish late surrender at every table.
Five checks at the table
Before betting, check these five details in the table’s published rules. The game name alone does not tell you every restriction.
- Free double eligibility: Which totals qualify, must the hand contain exactly two cards, and is it available after a split?
- Free split eligibility: Which pairs are excluded, how many hands are allowed, and can aces be re-split?
- Dealer 22 settlement: Which remaining hands push, and does player blackjack retain its winning payout?
- Dealer drawing and blackjack payouts: Does the dealer hit soft 17, and does player blackjack pay 3 to 2?
- Surrender and separate wagers: Is surrender offered, when is it available, and is any dealer-22 side bet clearly separate from the main game?
If a condition differs, do not assign that table the 1.04% house edge from Wizard of Odds or assume these calculation results apply unchanged.
Frequently Asked Questions
With a regular double, you fund the additional bet yourself. With a free double, the casino provides it: a win produces the same net profit, but a loss costs only your original cash bet.
Dealer 22 pushes remaining hands, returning the cash stake without a profit. It does not rescue a player hand that has already busted. Under the Nevada version, a player blackjack still wins.
There is no basis here for expecting a profit. Wizard of Odds gives a house edge of 1.04% under its rules. A positive expected value for one selected double does not make the whole game profitable.
